I have bought a new PC to process videos faster.
(Win 7, Intel Quad Core, Radeon HD R7870)

For some reason, the calibration path doesn't show after the frame 454, starts again at 8192, stops again at 8646.

This is really weird, can't understand the reason for it. I even tried completely installing a fresh windows 7, same result. Maybe it's because of some dependancy that I don't have because nothing else was installed on the PC yet. I'm running both recorder and studio in trial version for now.

So:
- in iPi Mocap Studio 2.2.1.145, tracking dots are only shown from frame 0-454, and 8192-8646 (for longer videos).
- it's the same for any calibration videos, also calibration videos from a different source (calibration video from this forum)
- changing the region of interest to frames 200-600 results in dots showing from 200-454.
- saving the scene and loading it on my laptop shows them as intended there, so the file works fine.
- reinstalling the entire PC didn't change anything
- the calibration itself seems to work, even without showing the dots.
- the missing dots are neither shown when unmarked, nor when marked (there is no blue marker for the invisible ones either).

Hello

There is a large probabilty that this issue is videocard specific. If so, we cannot do much because of not having such videocard at our hands.
Ensure you have the latest AMD video drivers.
